ADVERTISING DEVICE.

T 0 all whom it may concern:

Be it known that 1, CHARLES WV. WHALEY, of Indianapolis, count-y ofMarion, and State of Indiana, have invented a certain new and usefulAdvertising Device; and I do hereby declare that the following is afull, clear, and exact description thereof, reference be ing had to theaccompanying drawings.

This invention relates to an improvement on the construction set forthin my former application for Letters Patent, Serial No. 512,067, filedAug. 9, 1909, and consists particularly in automatic means for reversingthe driving mechanism at the end of the trip of a car when the device isused for a street indicator for railway cars, or at the end of acomplete series of operations thereof for whatever purpose it may beused.

The chief feature of the invention consists in providing an electricswitch in each of the rollers on which an advertising sheet containingthe signs or advertisements is rolled, so that when the sheet hasentirely rolled off one roller, a spring actuated switch will bereleased and operated and will modify the electric circuit so as tocause a reversal of the means for moving the advertising sheet, and whenthe other roller is entirely unrolled, the spring actuated switch issimilarly operated. Hence the reversing switches are located within therollers on which the paper is rolled and are actuated by the paperreleasing the same. In other words, when the paper winds on a roller itopens the switch, and when it unwinds, it closes the switch. Theparticular improvement herein described and claimed is not, however,necessarily limited to the construction set out in my former applicationbut may be applied to any indicating or advertising mechanism or otherdevice when a sheet of material is alternately rolled from one roller toanother.

The nature of the invention will be understood from the accompanyingdrawings and the following description and claims:

In the drawings Figure 1 is a central vertical section longitudinallythrough the device. Fig. 2 is a diagram of some of the electric circuitsin the device. Fig. 3 is a central vertical longitudinal section throughone of the metal rollers showing the switch closed. Fig. t is the sameas the left-hand portion of Fig. 3 showing the switch open. Fig. 5 is asection on the line 55 of Fig. 4. Fig. 6 is a similar section throughFig. 4c

with the paper wound thereon. Fig. 7 is a vertical section through themeans for con trolling the circuits.

A frame 10 carries two rollers, one, 11, near its upper portion, and theother, 12, in its lower portion, on which a sheet of paper or othermaterial 13 is wound from one to the other and vice versa. The two endsof the sheet are secured respectively to said rollers, and on said sheetany indicating means or advertisement may be placed.

The driving shaft 15 is located between the rollers and the frame, andthe upper roller is driven by it through the belt 10,:ind the lowerroller through the belt 17. Said shaft is composed of a plurality ofsections, the two ends being made of iron and separated by anintermediate brass section carrying an electric or other motor 18. Themotor section has on each end an electroanagnet 19 slidably mounted,having a core on which a clutch member 20 is secured that is adapted toengage a clutch member 21 on the adjacent outer section of the shaft.

The springs 22 tend to push the cores of the magnets and associatedclutch members outwardly into clutching position. The magnets, whenenergized, withdraw the clutch members associated with their cores fromengagement with. the clutch members 21. When only one magnet isenergized, the core and clutch member of the other magnet will drive thedevice in one direction and when said latter magnet is energized, thecore and clutch member of the first magnet will drive the device .in theopposite direction.

The motor is driven by current from the trolley wire adapted to run thestreet car in which the device is mounted, which, how ever, is not hereshown. In fact, the particular means for driving the intermediate section of the shaft 15 is rather immaterial to this invention, as thisinvention only relates to means for alternating the energization of theelectro-magnets 19 to bring about the reversal, and that will beunderstood from the diagram in Fig. 2. There the two magnets 19 areshown with the electrical connections between them and various otherparts. Before describing said diagram, however, the controller and alsothe rolls will be described.

The rollers 11 and 12 are constructed as indicated in Figs. 1 and 5,being partially tubular with a spring switch 25 secured at one end at aninner part of the roller, with the free end curved up and carrying themovable plate 26 that forms a section of the wall of the tube. Thespring is so arranged normally that it will hold said section 26 so itwill project outwardly beyond the external surface of the roller. Thefree end of the spring 25 is adapted to engage the contact piece 27 thatis secured within the roller and is in electrical communication with thewire 28, and the other end of the switch is in communication with thewire 29 that runs through to the binding screw 30, which is connected bythe strip 31 to a contact band 32. l Vhen the sheet of paper is rolledon the roll 11, it will depress the plate 26 to the position shown inFig. 5, and thus break the circuit and separate the free end of thespring 25 from the contact piece 27.

The controller consists of the ratchet wheel 35 with six surfacesthereon, the alternate ones being covered by plates 36. There are twopairs of contacts 37 and 38 adapted to engage one section of the ratchetwheel, and 39 and 40 adapted to engage the adjacent section. Therefore,one pair of these contacts is always in electrical communication becauseof engaging a plate 36. The ratchet on the pin or shaft 41 is looselymounted and is actuated by a solenoid extension 42 and an electro-magnet43.

Referring now to the diagram shown in Fig. 2, the current comes off thetrolley or live wire 50, over the wires 51, 52 and 53 to the lowermagnet 19, thence through wire 54 to the contact 40 and through plate 36on the ratchet 35 to contact 39, and thence over wires 55 and 56 to theground wire 57. The current through that circuit will energize the lowermagnet 19, which we will assume to be the same as the left-hand magnetin Fig. 1. Therefore, it will cause the motor 18 to operate one of therollers, say 11. Both rollers 11 and 12 have nearly all the time aportion of the sheet of paper rolled on them tightly, so that bothswitch actuating plates 26 are held down in the position shown in Fig.4, or the lower part of Fig. 2, and, therefore, are in circuit breakingcondition and do not interfere with the operation of the electromagnet19 just referred to. But as soon as, say the upper roller 11 has thepaper wound ofi of it, the switch actuating plate 26 immediately assumesthe position shown in Fig. 3 and upper part of Fig. 2. That closes thefollowing circuit. The current passes from the main wire 50 over wire 60to wire 28, and thence through the contact 27 and switch 25, wire 29,screw 30 to the band 32, from which the wire 61 leads to the wire 62that goes to the magnet 43. Current passes through magnet 43 and outover wire 58 to the ground. That will energize the magnet 43 and thesolenoid extension 42 will operate the ratchet 35 and move it one notch.That will throw out the circuit above described for actuating the lower1nagnet'19 and throw in a circuit through contact points 37 and 38,which actuates the upper magnet 17 or the right-hand one in Fig. 1, andthat will stop operation of the upper roller and start the operation ofthe lower roller and reverse the movement of the sheet of paper. hen thepaper starts to wind on the upper roller, the switch 25 therein will beactuated and break the circuit, which actuates the magnet 43. Then thecurrent will pass from the live wire 50 through wires 51, 52 and 7 0 andupper magnet 19 and wire 71 through contact 37, plate 36. contact 38,and out through wire 55 to the ground. This will continue until thesheet is all wound on the upper roller, and then the circuit in thelower roller is closed by the spring switch 25, and immediately acurrent passes from the live wire 50 through wire 51 down to and throughthe lower roller and out over wire 80, through wire 62 down to themagnet 43, and out through wire 58 to the ground. Then the magnet 43will give the ratchet 35 another step movement.

What I claim as my invention and desire to secure by Letters Patent is:

1. An advertising device including a pair of rollers, an advertisingsheet with its ends connected to said rollers so as to be wound off andon the same alternately, electrical means for reversing the direction ofmovement of the rollers, said rollers having a por tion thereof cutaway, an electrical springclosecl switch mounted in the cut-away portionof the roller and which is in electrical communication with the meansfor reversing the movement of the rollers, and a plate curvedconformedly to the surface of the roller that is secured upon saidswitch, the arrangement being such that when the sheet of paper is woundon said roller, it will force said plate and switch down and open thecircuit, but when the sheet of paper is unwound from said roller theswitch will close.
